Musique Sans Frontieres

One normal afternoon inside Mother Base, Azusa was doing her usual fishing on the deck; so far she didn't have a single fish since she started. She stared at the sky then to the horizon and sensed something was about to happen later, particularly about the weather as the winds became stronger in the last hour. Besides that, there was something still bothering her, as if a bigger problem was approaching. She was occupied in the thought when a fidgety Yui showed up hugging her combat shotgun like she does with her guitar.

"Azu-nyan...help me..." Yui pleaded with teary eyes as she sat beside Azusa.

"A-Ah..."

"Snap out of it, Azu-nyan!" Yui said as she hugged her.

"Huh? Is there something wrong, senpai?"

"I feel like...I'm being watched by someone..."

"D-Don't you mean...like a stalker?" Azusa uttered in surprise, almost dropping her fishing rod. "A-A s-stalker..."

"Ssshh! Not too loud!"

"Ah...Yui-senpai, is there anything..."

"It's been more than a week now...and...I can't live like this!"

"...More than a week?"

"Although Mio-chan is the only girl inside Mother Base that has a fanclub, I won't be surprised if someone would actually take interest in you." Sawako said, appearing out of nowhere.

"Sensei? D-Don't show up like that! You're ruining the mood here!"

"Hm? I did some arrangements with that blonde Parisienne about costumes for future events. Something wrong?"

"Nothing sensei...you just scared me..." Azusa replied softly. "Wait...I didn't ask what you did earlier..."

"Well, about Yui's problem; it can't be helped. We just need to be more cautious."

"Uh...Yui-senpai, why do you have that thing with you?" Azusa asked, pointing at Yui's custom combat shotgun.

"Oh...you mean Pasu-chan? She's the one who will act as my very own, personal deterrent!" Yui replied.

"She'll blast them flying with rubber slugs!"

"Y'know, even if you use rubber shots, you could still kill a person, especially if aimed at a vital part." Sawako explained.

"I knew you'll gave it a name someday..." Azusa remarked then thought of something about the shotgun's name. "Wait, you named your guitar 'Gitah' which is very straightforward. Where the heck Pasu came from?"

"Pasu...SPAS..."

"Oh...that's..." Azusa uttered; somehow confused on the shotgun's bizarre name. "Wait, SPAS is an acronym, right?"

"Maybe I should change it to Pasu-nyan instead?"

"No way!" Azusa quickly turned down the suggestion of her senpai. "Go on with Pasu-chan."

"Hmm...I could see that you girls have your weapon of choice, eh?"

"Yes. How about you, sensei?"

"Well, in action movies, I do love EXPLOSIONS; lot's of them. So, I prefer rocket launcher much. If I'm not holding one, you'll see me holding something that spews out hundreds of rounds per minute."

"Oh, hello everyone. What's up?" A voice greeted them from behind.

"GET AWAY!" Yui cried, quickly turned to the person and fired a shot from her shotgun. She opened her eyes to see Ritsu squirming in pain on the floor and a flabbergasted Azusa.

"Yui-senpai...you fired at Ritsu-senpai in point-blank range? What were you thinking!" Azusa rushed to help Ritsu.

"You...idiot!" Ritsu uttered before she lose consciousness.

"...Private Ricchan, signal lost."

"Wow, that's gotta hurt...a lot..." Sawako said. "Well...I gotta go now."

"Wait, you're leaving us?" Azusa asked in surprise then the moment she turned her head around, Sawako was nowhere to be found. "SENSEI!"

With the help of nearby soldiers, they immediately sent the drummer to the sickbay. They waited for a few minutes while an on-duty doctor checked Ritsu's condition.

"She had a large bruise in the abdominal area due to the strong impact, considering that you discharged a rubber slug at point-blank range. Thank God that you didn't used a more lethal one."

"P-Please...you don't have to repeat what happened earlier..." Yui pleaded with tears overflowing on her eyes.

"Yui-senpai..."

"H-Honestly, it was all just an accident!"

"You don't have to worry so much, she's unconscious, but she's safe from harm." The doctor said, alleviating the grief of the ditzy guitarist.

"That's a relief...thank you." Yui said then she turned to Azusa with her usual smiling face. "Want to do something else, Azu-nyan?"

"You recover that quickly?"

"I think I'm going to cry again..."

"I-I dunno..." Azusa quickly replied. "More importantly, where's Sawako-sensei? She's just here..."

"Let's get some snacks in the mess hall!" Yui said while pulling Azusa's hand.

"We just ate lunch!" Azusa protested.

"Isn't that great?"

"...If that will make you happy, then, okay."

"Oh...let's visit the next best thing then!"

They got out of the sickbay and noticed some changes in the sky, which was now turning darker as time passes. Yui suggested to visit Mother Base's greenhouse, where almost all of the cultivated crops were grown and harvested for the soldier's disposal. Apparently, she sometimes helped the personnel working in the area when got nothing to do and receive fresh fruits as payment. She does it when got nothing to do and eventually got accustomed to the activity of hers.

It was quite unexpected for Outer Heaven to build an additional plant for plant cultivation. Although, they had a separate operating base in Costa Rica which had a similar function, but the base was subject to sudden raids, which forced them to make one inside Mother Base instead.

As soon as they opened the glass doors, the scent of freshness welcomed them. There were a few workers around, tending the crops or harvesting ripe ones.

"Ta~da! We're here!"

"I never got the chance to visit this place..." Azusa said as she glanced at the different kinds of plants grown in the greenhouse.

"Yup, you're too busy helping in the intel team or fishing."

Yui suddenly grabbed Azusa's arm. "There it is again, Azu-nyan..."

"Stalker? Relax it's just your..."

"Oh, good afternoon, Yui-chan, Azusa-chan." A girl greeted them with a garden spade in her hand.

"NOOO! You won't get me that easily!" Yui turned around and fired another rubber slug to the girl but was quickly evaded. The shot instead hit another unwary person behind who was carrying a sack of fertilizer.

"Uh, Yui-chan, are you okay?" Tsumugi asked.

"A-Ah, sorry, Mugi-chan! I...didn't mean to..." Yui stammered. "I thought that you were holding a knife and..."

"That's okay...no harm done." The keyboardist replied with her usual smile.

"Er...senpai..." Azusa pointed to the injured man lying on the floor.

"Oh my..."

"We got to bring the guy to the sickbay!" A worker wearing a scarf said in panic as he checked the condition of the unfortunate victim.

"Damn, it think something inside me died just now..." The man uttered.

"Uhm, Ms. Kotobuki, can you stay here for awhile? We won't take long." A woman with a long braided hair said.

"Oh, sure. No worries." Tsumugi replied.

"So, Mugi-senpai helps here too, huh? You sure enjoy a lot of stuff here..."

"It's best to enjoy them while we're still here. To be frank, I love gardening too."

"For how long?" Azusa asked with an uninterested face.

"I don't know myself..."

"Well, about Yui-senpai problem..." Azusa said, shifting her eyes to Yui. "She told me about someone has been following her around but I've never seen the person so far..."

"Hmm...could it be that someone who is interested in her?"

"Mugi-senpai, you think like Yamanaka-sensei..."

"I already sent two persons in the sickbay. At this rate...I...I..."

"Calm down, Yui-senpai!"

"I guess you should rest in the room for awhile Yui-chan...maybe you're just tired..." Tsumugi suggested.

"Maybe..."

"She's right, senpai. You just need some rest..." Azusa said. "Or you just ate expired cookies again..."

"I'll finish my duties here. Let Yui-chan rest in the room and I'll meet you in the mess hall during dinner."

"Hmm...senpai, I don't know what I should do..."

"I-It's okay..."

Following Tsumugi's suggestion, the two went to their room in the living quarters for Yui to rest for an hour. After their dinner in the mess hall, they went straight to their room. Ritsu rejoined the others after getting a good rest from her injury. Yui felt more better now after a good nap and meal but still vigilant for everyone around her, not to mention that she again introduced another unlucky visitor to the sickbay during dinner with her shotgun.

The feeling of being watched never subsided but she felt more secure inside their room and finally could release some tension. They were having their usual tea time when everything became dark after an earsplitting thunder then the scream of Mio followed, making neighboring rooms panic as well.

"Eh? The light's went off?" Yui asked the obvious.

"Mio-chan, it's alright." Tsumugi comforted.

"This storm sure is something." Ritsu said casually.

"This never happened before...maybe it's a sabotage..." Tsumugi speculated.

"It's just the storm, Mugi." Ritsu pointed out.

"Yes...maybe the lightning struck the base's power supply..."

"M-Mugi, don't say things like that..." Mio said anxiously. "Can someone hand over a flashlight?"

"I don't mind since I have this whole plate of cookies for myself." Yui said happily.

"Should we go outside to check what's happening?" Mio asked worriedly.

"Nah, we should stay here. They'll fix it..." Ritsu said, lying down on the floor lazily. "You're too worried..."

"Give me a flashlight then." Mio said in an irritated tone.

"Yui-senpai? Could you pass the cookies?" Azusa asked when she noticed that the guitarist soloed the whole plate of cookies but almost a minute already passed and there was no any response from Yui.

"Err...Senpai? Don't you dare hide those cookies from us!"

Out of the blue, the whole room turned bright orange when Tsumugi lit a gas lamp.

"Where did that came from?" Ritsu asked.

"Oh, I just remembered keeping this one just now."

With the lamp illuminating the room, Azusa looked around for Yui but there was no trace of her inside.

"Y-Yui-senpai's missing!" Azusa anxiously announced. "She was here a minute ago!"

"How could that happened?" Tsumugi worriedly asked as Mio became frozen solid in fear.

"W-What? Someone took her?" Ritsu exclaimed. "A person actually snuck inside our room and took Yui without us noticing?"

"T-That's impossible, no one could ever pull a trick that good!" Azusa followed. "Lucky that we're in an offshore plant, the culprit won't get away that easily."

"Is it just me, or it's gotten cold around here..." Ritsu said then noticed that the sliding window at the far end of the room was slightly open. "Oh, the window's open. I'll close it..."

"Oh...sure..." Mio said. "Wait...did you just said that the window's open?"

"Yep, something wrong with that?"

"Idiot!" Mio ran towards the window and peered below, allowing the cold wind and rain to enter their room. There was a rope with its hook firmly attached at the roof of the building. Their room was three stories high and seemed unimaginable how the whole process happened, not to mention that the storm made things harder.

"What did you found?" Tsumugi curiously asked.

"A grappling hook?" Ritsu said. "Whoever kidnapped Yui, he's insane! No one could climb that fast in this weather. How the heck did they got down together?"

"Wait...something's moving below!" Mio noticed an obscure figure carrying someone on its back and now fleeing to safety. "They're getting away! Ritsu, do something!"

"What? I can barely see them." Ritsu replied. "Besides, submachineguns are pretty useless in longer distances.

"You're useless..."

"What? Then, you go ahead and see if you could hit them!"

In desperation, Azusa slammed onto Ritsu, who nearly fell from the window, and carefully aligned the sight's of her sniper rifle to the target. "I can't aim properly, senpai, don't move!"

"Ack, why use me as a human stand!" Ritsu complained.

"Azusa, you might hit her!" Mio warned, knowing that the abductor was carrying Yui on its the back.

"Don't worry, it's only traquilizer rounds." Azusa replied calmly then fired a few shots to the abductor but her firing position restricted her to get a good aim to the target and eventually disappeared from her field of vision.

"If you only stop flailing around!"

"Ack...my stomach!" Ritsu exclaimed in pain as she remembered the bruise that she got from Yui's shotgun. "Have you got concern over the injured like me?"

"Hurry! We need to catch up!" Tsumugi said, changing her clothes to the standard MSF uniform.

Their conversation halted when Sawako kicked the door open and yelled at them with extreme ferocity. Himeko followed with the other soldiers from nearby rooms alarmed after hearing the gunshots. "What's with the racket here? I can't sleep with all of these noise!"

"Oh, what happened here?" Himeko inquired as she saw their drenched, anxious faces.

"Yui-chan's gone!" Tsumugi replied as they prepared themselves for the pursuit.

"...What? How could..." Himeko dropped the pillow she was holding.

"So...?" Sawako asked as she gave them a blank look for some seconds.

"Have a bit of concern on your students!" Tsumugi said as she perform a headlock to Sawako, imitating Ritsu. "Ah...I always wanting to do this too!"

"Mugi, That's my job!" Ritsu said, still clutching her stomach.

"Can't breathe..."

"Is that true? We need to find Yui now!" Himeko said in panic as she rushed back to her room.

"We should also report this to Miller-san!" Mio suggested.

"Shouldn't we report the situation to Snake instead?" Ritsu quickly replied.

"But...But...I'm scared..."

"Fine, I'll go to the command center and find Snake while you find the person who took Yui..."

"That's totally unfair!" Mio protested.

"There's no need to panic. We're in an offshore plant, plus, there's this storm. The kidnapper won't be going anytime soon." Sawako said reluctantly.

"I...pointed that out earlier..." Azusa mumbled.

"Easy for you to say." Ritsu said. "Are you going with us?"

"You girls go ahead...I need my beauty sleep..." Sawako drowsily replied, walking back to her room.

"Some other time, 'kay?"

"Well it seems that Sawa-chan is not involved in this..."

"What? If I were to kidnap one person from you girls, she will be definitely the last!"

"Why would they kidnap Yui in the first place anyway?" Mio asked.

"Maybe for the enemy to get information from her..." Tsumugi replied. "I shouldn't be thinking things like that now..."

"T-Torture?" Ritsu exclaimed. "But that's...she don't know anything! She's totally clueless!"

"Yui's going to be tortured?" Mio asked in surprise, tending not to believe what Ritsu said. Unpleasant things started to form in her head.

"The bad guys would slowly drain her poor soul until she gives in using horrid, unconventional forms of torture materials that will surely..."

"Shut up, I heard enough!" Mio interrupted with a strong punch to the face of the drummer.

"Ow...and then...CRASH, MINCE, BOOM!" Ritsu continued with exaggeration.

"You want some more, Ritsu?"

"Could it be its one of Yui's admirers then?" Tsumugi guessed as the two looked at her with wide-opened mouths.

"That's too...awkward..." Ritsu replied.

"Enough with this small talk...please..." Azusa spoke in a loud voice.

"Oh, great, we wasted a few good minutes there..."

Mio and Tsumugi went to the command center to inform the situation to Snake while the rest went to find the kidnapper. The rest, together with some other soldiers who volunteered to help them, checked the buildings near the living quarters, hoping that they could catch up. Ritsu's group soon entered the mess hall, equipped with night vision goggles and their weapons at the ready. The occasional flash of lightning illuminated the building.

"Why do I get the feeling that this happened before?" Tsumugi asked.

"It's just you, Mugi." Ritsu replied. "Why on earth are we checking the mess hall?"

"Well, places you least expect to appear are the best ones to look at first."

"W-Who's that?" Azusa asked as she heard footsteps from their right, slowly closing in. They soon saw someone walking towards them, then stopped as the group aimed their weapons at the person.

"Don't move any closer, or I'll shoot." Himeko warned with her pistol at the ready.

"You won't get away now, bastard!" Ritsu bursted out. "This is for kidnapping Yui!"

"Yui-senpai!" Azusa cried upon recognizing the ditzy guitarist in the darkness, hugging her tightly.

"Eh? Well, I'll be damned...it's Yui..."

"We're so worried..."

"It's good to see you, Azus...Azu-nyan." Yui nervously replied.

"Are you okay, senpai?" Azusa asked.

"I...managed to ran away from the kidnapper...I'm scared..."

"Don't worry, you're safe now."

"I'll report this now to the others." Ritsu said, bringing out her radio.

They regrouped at the command center's lounge where Snake and the others patiently waiting for the news. At that point, only the backup power supply was providing electricity to the vital equipments, facilities and emergency lighting throughout the vulnerable fortress. Although, attackers should think thrice. Yes. Thrice, or ZEKE won't be happy.

"We found Yui!" Ritsu announced.

"Thank goodness..." Mio said in relief. "Well, that solved one problem..."

"What about the kidnapper?" Tsumugi inquired.

"We haven't found him yet."

"What's the status?" Kaz asked the soldier who just recently arrived after Ritsu's group got in the lounge.

"Sir, I'm positive that the power failure is not caused by the storm. It is more of a sabotage." The soldier informed, soaked from the rain outside. "We are already doing the necessary repairs and the power will be back shortly since the damage is not that heavy."

"W-What? How could that happened?" Kaz uttered in surprise. "Is it a spy?"

"W-We got ourselves a spy in Mother Base?" Mio asked surprisingly.

"If he's a spy, then it would be a disadvantage for his part, right? I mean, naturally, a spy won't reveal his cover."

"Oh...you have a point there..."

"We also found fragments of a small explosive device with some kind of timer." The soldier added.

"Hmm...I presume that he used the storm as an excellent cover to make it less noticeable." Snake said.

"But there's something that is not clear..."

"What is it, Boss?" Kaz asked.

"If his mission was to sabotage the base...why would he set a timer in the first place?"

"True...he could have used much powerful explosives. I'm sure there's some sort of an ulterior motive on this one..."

Tsumugi tried to assemble the pieces and came up with something although it was quite vague. She then spoke confidently to grab everyone's attention, breaking the silence in the lounge. "It's definitely connected to Yui's kidnapper!" Everyone stared at her blankly before she continued. "The person sabotaged the power supply must be the same one who kidnapped Yui."

"Maybe, but he could have picked someone else..." Kaz pointed out. "Someone with more...info..."

"I guess you're right..."

"The true motive is still unknown..." Azusa said then noticed a pale and nervous Yui behind them.

"Yui-senpai...are you sure that you're feeling okay?"

"It's nothing..." She replied softly, shivering in her drenched uniform.

"For goodness sake, why not ask Yui? She's the one who was kidnapped!" Ritsu shouted then turned to the guitarist. "Yui? Did you saw the face of the kidnapper?"

"Ah...well, he was wearing a balaclava..." Yui nervously said.

"This won't get us anywhere at all!"

"Admit it...you're not Yui." Sawako appeared from the darkness as everyone else looked at her confusingly with a 'Where the hell did you spawn?' look. "Ui-chan...give up now."

Silence filled the room as if they tried to absorb what Sawako just said.

"W-What? Ui? But that's..." Mio stammered.

"B-but sensei, I'm Yui." The girl insisted.

"Then who's this?" Sawako pointed at the person lying on the couch.

"There are two Yuis?" Ritsu said in astonishment.

"Idiot! Of course, one is an impostor!" Mio replied from the nonsense of the drummer.

"Where did you found her?" Tsumugi asked.

"In your room, quite clever, no? She was carrying a mere decoy...the real Yui is still in the room but tranquilized..." Sawako explained in somewhat a detective fashion.

"But, she's not in the room!" Azusa replied as she recalled that there was no trace of Yui in their room.

"Oh, I forgot about this..." Sawako showed them a portable device that they immediately recognized.

"Is that a stealth camouflage?" Tsumugi noticed.

"I don't get it..." Ritsu whispered.

"What part you don't get?" Sawako asked as she heard the drummer.

"What the hell are you doing in our room?"

"Well...about that...I was just checking some leftover snacks and..."

"So, that's why some of our snacks magically disappears!"

"Yui-senpai, we owe you an apology..." Azusa said in a soft voice. "All those days of arguments..."

"If you think of it, she might have used a better way since she got a stealth camouflage of her own but I guess she's more concerned in her sister's safety and come up with something more harder on her part instead."

"That's sisterly love for ya." Ritsu said.

"I don't know if Yamanaka-sensei is simply amazing or not." Mio mumbled to herself.

"I...I..." Ui fell to the ground, admitting her defeat. "You got me sensei..."

"You're Yui's sister?" Kaz said in disbelief. "Oh, god...what's with the sudden appearances of these girls..."

"It's quite obvious, idiot. They're almost like twins, y'know?" Ritsu said. "But, yeah, I'll definitely agree about us being teleported in this time."

"This is totally absurd."

"I only made things worse for her...maybe if I didn't followed her here..." Ui sobbed.

"Why not join us?" Tsumugi offered.

"So we're recruiting another one, huh?" Kaz just sighed. "Boss, your call..."

"Well, do we have other choices now?" Snake asked as he lit a cigar. "Oh, can you make us some maté too?"

"When I learned that Onee-chan is here. I took the chance when they chose me to gather intel about this place and plan bringing Onee-chan with me on my way back but...I shouldn't did that in the first place..."

"Who sent you here, Ui-chan?" Azusa inquired.

"C-CIA..."

There was an eerie silence afterwards...

...

...

...

Ritsu stared at Yui's sister with an open mouth. "Wai...What?"

Kaz himself was also dumbfounded. "Can I use the bathroom?"

"I can't believe you joined the CIA just to find Yui..." Mio said, seemed quite more commending Ui.

"...Is that a bad thing?"

"Think before you do something!" Ritsu shouted which made Ui wince a bit. "How did you get inside?"

"Oh, my insertion method? I simply blend in myself in the group of new recruits."

"You're insane..."

"Maybe we should be more cautious about our recruitment methods..." Kaz mumbled.

"To think of it, your the one handling that now..."

"Are you saying something, Boss?"

"I watched Onee-chan the whole time; the moment she wakes up until she sleeps. I learned all about the base doing that, but, I guess she noticed my presence and felt really uncomfortable. I...I..."

"I'm sure she won't be mad at you. In fact, she will be happy seeing you here..." Azusa said with a smile.

"...Really?"

"At least, you aren't that desparate enough to hijack ZEKE just to fetch your older sister." Kaz said uneasily while gazing outside.

"Um...to be honest, that was my last resort..." Ui replied shyly. "They've ordered me to hijack your bipedal weapon system but don't worry, I have no intention of doing that."

"You somehow reminded me of this particular 'highschool' girl..."
